Sophie is a year younger than Elena. My blondies are short, I tell ya!
So, after spending a little over $30 for this experience, which the girls were tired of after 20 minutes (girls don't like to sweat apparently), I decided this tradition needed some revising.
After we'd been there for 45 minutes, with me encouraging them to "go back and play" several times, Sophie asked Elena: "Can we go back to your house to play?"
That confirmed my plan. Next time around, the birthday kid will decided who they want to spend the day with and they can play together all day at our house (or the park) and we'll take the two out to eat somewhere fun. Less cost, which you know I love, and more quality time together. I wish I'd thought of it a year ago!
